XPRSnlpgetformula, XSLPgetformula

Purpose
Retrieve a single matrix formula as a formula split into tokens.
Topic area
Problem Information
Synopsis
int XPRSnlpgetformula(XPRSprob prob, int row, int parsed, int maxtypes, int *p_ntypes, int type[], double value[]);

int XSLPgetformula(XSLPprob prob, int row, int parsed, int maxtypes, int *p_ntypes, int type[], double value[]);
Arguments
prob 
The current problem.
row 
Integer holding the row index for the formula.
parsed 
Integer indicating whether the formula of the row is to be returned in internal unparsed format ( parsed=0) or parsed (reverse Polish) format ( parsed=1).
maxtypes 
Maximum number of tokens to return, i.e., the length of the type and value arrays.
p_ntypes 
Will be set to the length of the formula, including the XPRS_TOK_EOF token.
type 
Integer array to hold the token types for the formula. May be NULL if maxtypes is zero.
value 
Double array of values corresponding to type. May be NULL if maxtypes is zero.
Example
The following example displays the nonlinear formula in row 2, column 3 in unparsed form: 
int ntypes, n;
int *type;
double *value;

XPRSnlpgetformula(prob, 2, 0, 0, &ntypes, NULL, NULL);
type = malloc(ntypes * sizeof(int));
value = malloc(ntypes * sizeof(double));
XPRSnlpgetformula(prob, 2, 0, 10, &ntypes, type, value);

for (n = 0; type[n] != XPRS_TOK_EOF; n++)
  printf("\nType=%-3d  value=%lg", type[n], value[n]);
Further information
The type and value arrays are terminated by an XPRS_TOK_EOF token.
